2508051216Y0

Overview

The Fair-Rite 2508051216Y0 is a multi-layer ferrite chip bead designed for surface-mount applications. It utilizes an 0805 package (2012 metric) to provide compact EMI suppression in high-density circuits. The component exhibits a nominal impedance of 120 ohms at its rated frequency, with a maximum DC resistance of 100 milliohms and a tolerance of 25 percent. It supports a maximum DC current of 300 mA and operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Multi-layer construction enables effective electromagnetic interference suppression in a compact form factor
• Surface-mount termination style facilitates automated assembly processes
• High-temperature stability ensures reliable operation across extended industrial ranges

Applications

• Electromagnetic interference filtering in portable electronic devices
• Signal line protection in consumer electronics
• Power supply noise suppression in compact circuit boards

Procurement Notes

Verify the specific manufacturing lot and RoHS compliance status directly with Fair-Rite Products Corp. or authorized distributors before procurement. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Ensure the 300 mA current rating meets your circuit's operational demands. Request official datasheets to validate impedance characteristics at your target operating frequencies.

Selection Notes

Select this component when space constraints require an 0805 footprint for EMI filtering. The 120 ohm impedance provides targeted attenuation for specific noise spectra. Verify that the 300 mA current handling capability exceeds your circuit's peak load. Consider the -55°C to +125°C operating range for environmental suitability. Compare against other multi-layer beads if higher current or different impedance values are required.

Part Context

This part belongs to Fair-Rite's series of multi-layer ferrite chip beads, which integrate magnetic material layers within ceramic substrates. These components offer superior performance compared to traditional single-layer beads in small packages. The 250805 series specifically targets applications requiring precise impedance control and high current handling in minimal board space.
